Appiication November 23, 1951, Serial No. 257,817 1 Claim. (Cl. 24ii-123) This invention relates to lighting devices and has special reference to a torchere.

In the method now generally used for manufacturing devices of this character, there is provided a relatively shallow bowl from the center of which depends a neck or hub integral with the bowl. In these devices the material used is of translucent character such as glass or other like materials. Due to the peculiar shape of the device the heat from the lamp used in connection with 4such lighting arrangement causes unequal expansion of the body of the bowl and the neck. Consequently, fractures due to this unequal expansion frequently take place at the junction of the neck and bowl.

One principal object of the present invention is to provide a novel construction of torchere having a shallow bowl-like body and a metallic neck or hub depending from and carried by the body. In this construction, the bowl is, of course, of translucent material.

ln the joining of a metal hub to the body the question of unequal expansion again arises. Another important object of the invention is to provide novel means forso connecting the metal hub with a bowl of glass or the like in such manner that while the connection will be rm, compensation is had for the unequal expansion of the glass and metal.

A further object of the invention is to provide a connection between the hub and bowl of such a device whereby the hub may be made of tubular form and without the necessity of providing threaded means for attaching the hub and bowl together.

A still further object of the invention is to provide a novel hub and bowl connection wherein a snap ring is utilized to produce a firm connection while at the same time permitting unequal expansion of the bowl and hub without danger of fracturing the bowl.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing and particularly claimed.

In the accompanying drawing, like characters of reference indicate like parts in the several views and in which:

Fig. 1 is a side elevation of cordance with this invention,

Fig. 2 is a fragmentary diametric section taken through the device, and

Fig. 3 is a section from line 3-3 of Fig. 2.

In the invention shown in the accompanying drawing, there is provided a shallow bowl 10, which is made of glass or other suitable translucent material. Bowl is a torchere constructed in acprovided centrally of its bottom with a circular opening i1. The metal hub which carries the bowl id has a lower end 12, ot truste-conical form which dares outwardly adjacent its upper end as shown at 13. This stem or hub is made of thin metal ol uniform thickness throughout and at the upper extremity of the flared portion the metal is extended inwardly as at .ld and vertically upward as at 15 to form a cyiindricai portion. At the upper edge of the cylindrical portion l5 the metal is extended outwardly as at in and upwardly as at i7. The arrangement of the metal at the parts iid, 15, and i6 produces an external groove in the hub. At the upper end of the part i7 the metal is iiared outwardly as at i3 to ht on the inside of the bowl i@ arcund the hole or opening 11 and it is to be noted that a slight spacing exists between the periphery of the hole i1 and the upwardly extending wall portion 17' of the hub, this spacing being indicated at E9. in connection with the neck or hub, there is provided a washer 2d, which tits on the outer side of the bowl around the opening ii. This washer is aligned with the hub portion la. A split ring 2t is seated in the groove of the metal hub and it will be observed, from Fig. 2, that this split ring engages against the inner periphery of the washer 2@ so that the washer may expand slightly when heated without becoming detached from its support of the bowl. it will further be noted that by means of this construction the flange i@ is integral with the body of the hub and that there is not required any screw threading in the c011- ncction between the hub and the bowl body.

As clearly shown, spring fingers 22 are formed in the lower part of the hub and extend upwardly and inwardly so that the hub may be tted on the upper end of a lamp standard.

It is obvious that minor changes may be made in the form and construction of this invention without departins from the material principles thereof. i t is not therefore desired to coniine the invention to the exact form here shown and described but it is desired to include all those forms which may come within the scope of the invention as claimed.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

In a torchere, a bowl body having a centrally disposed opening in its bottom, and a tubular sheet metal hub detachably secured thereto, said hub adjacent its upper end being first bent inwardly and then vertically and then outwardly to provide an annular groove at the outer side of the hub, an upward extension above ,said groove within the bowl opening and spaced from the edge thereof and an outward extension at the upper terminal end of the hub overlying the upper surface of the bowl adjacent the opening therein, a washer at the underside of the bowl alined with the outward extension that forms the top wall of the annual groove and a snap ring in said groove for holding the washer engaged with said bowl and the bowl and hub assembled.
